Colonization dynamics of periphytic diatoms in coastal water of Qingdao, northern China [PDF]
本研究旨在研究青岛近岸周丛硅藻群集过程的动力学特征。采样地点为青岛奥林匹克帆船中心,采样方法为悬挂载玻片人工基质法。在2014年的5月至6月进行为期一个月的预实验以确定采样策略。结果表明,在设定的1米和3米采样水层,尽管周丛硅藻群落结构相似,但1米水层的物种数高于3米水层。在整个周丛硅藻群集阶段,分类学多样性指数表明了两水层有高度的差异性(差异系数>10%),分类学差异指数、平均分类学差异指数和分类学差异变异指数表明在群集7天以后周丛硅藻群落具有了较高的相似性(差异系数The temporal ...

ABSTRACT Managing diabetic wounds requires simultaneously addressing their infectious, oxidative, and regenerative impairments. To address this, this study integrates a piezoelectric BiOCl@CuSe heterojunction (PFM‐verified) into an injectable F127/HA hydrogel, creating an ultrasound‐responsive smart dressing.

Study on latitudinal gradient of species diversity in forest communities [PDF]
森林群落结构和物种多样性的空间分异规律一直是生态学研究的热点问题。近年来,关于森林群落结构的描述与物种多样性的测定方法等研究也都有所发展,但这些研究大多是对森林生态系统的定性描述,而且方法不一,数据之间也缺乏可比性。 群落的组成结构是群落的重要标志,研究群落结构是研究群落物种多样性意义的理论基础,所以从群落组成结构的角度来探讨生物群落的物种多样性具有重要的意义,为进一步深入研究生物多样性功能及确定功能群提供理论基础 ...

ABSTRACT Integrating light emission and electromagnetic wave (EMW) absorption into a single material opens up possibilities for multienvironmental applications. Herein, we propose a novel “molecular engineering‐pyrolysis conversion” strategy to construct a bifunctional system with tunable photoluminescence and efficient EMW absorption performance.
